1. A power storage device, comprising:
- a stack having positive electrodes and negative electrodes stacked on top of each other with electrolytes interposed in-between and in which a positioning hole is formed, the positioning hole penetrating the stack in a stacking direction in which the positive electrodes, the negative electrodes, and the electrolytes are stacked;
a positioning member that is inserted into the positioning hole; and
a terminal portion that is formed at an end of the positioning member in an inserting direction in which the positioning member is inserted into the positioning hole, whereinthe terminal portion is provided with an electric wire, the terminal portion indirectly contacting a surface of one of the positive electrode or the negative electrode of the stack.

Abstract
A power storage device has a stack including positive electrodes and negative electrodes that are stacked on top of each other with electrolytes interposed in-between. A positioning member is inserted into a positioning hole that is formed in the stack so as to penetrate the stack in the stacking direction. A terminal portion is formed at an end of the positioning member in the inserting direction.
